Abstract

A surgical access apparatus includes a liner base and an access housing for positioning outside the body. The liner base includes an inner member adapted for insertion through an opening within body tissue for positioning within the body; a sleeve member connected to the inner member and dimensioned to extend from the inner member through the opening within the body tissue, and a plurality of tensioning elements connected to the inner member and associated with the sleeve member to impart a tensioning effect on the sleeve member. The access housing includes a first element and a second element. The second element is operatively connected to the tensioning elements and adapted for rotational movement relative to the first member to cause the tensioning elements to displace the inner member toward the access housing and to cause the sleeve member to engage and retract tissue defining the opening within the body.

Claims

exact text as granted — not AI-modified
1. A surgical access system, which comprises:
 an access member including:
 lower and upper segments; 
 a sleeve segment including a flexible membrane extending between the lower and upper segments, the sleeve segment dimensioned and adapted for positioning through a tissue tract to substantially line the tissue tract; 
 an access housing mounted to the sleeve segment, the sleeve segment and the access housing defining a passage therethrough; and 
 an access seal mounted to the access housing, the access seal dimensioned and adapted to establish a substantial seal about an arm or hand of a clinician; and 
 
 a trocar adapter releasably connectable to the access housing in the absence of the arm or hand of the clinician, and having;
 a trocar sleeve dimensioned for reception of a surgical instrument, the trocar sleeve at least partially disposed within the passage of the access member when the trocar adapter is mounted to the access housing; 
 a trocar housing having a trocar seal dimensioned and adapted to establish a substantial seal about the surgical instrument, the trocar sleeve extending from the trocar housing, the trocar adapter including an adapter base, the adapter base adapted to releasably mount to the access housing of the access member. 
 
 
     
     
       2. The surgical access system according to  claim 1  wherein at least one of the trocar housing and trocar sleeve are connected to an internal area of the adapter base.
